1. You cannot open trades based only on the intersection of +DI and -DI. It is also necessary to focus on the main indicator line and other signals. If at the moment of crossing the index line is between 30% and 40%, it is better to ignore the signal.
2. It is impossible to open trades without their insurance by a stop-loss order or trailing.
3. It is undesirable to use the instrument on a timeframe below H1.
4. It is possible, but undesirable, to open deals at the moment of crossing the dotted lines when the index is above 40-50%. At this moment, there is a possibility of a change in the direction of the trend. But since the ADX indicator shows high market activity, its continuation is also possible.
